Wetted Wall Columns
ANTICO WettedWall™ is designed for precise gas–liquid mass transfer studies and small-scale absorption operations using a well-defined liquid film on the inner wall of a vertical tube.
The working principle involves liquid flowing down the inner surface of a smooth vertical tube as a uniform film while gas flows either counter-currently upward or co-currently downward, providing a well-characterised and controlled gas–liquid interface. The system includes a precision vertical column, liquid feed and overflow arrangement, gas inlet and outlet, and temperature control jacket. It is primarily used as a research and measurement tool for determining fundamental mass transfer coefficients, diffusivities, and reaction kinetics. The simple and precise geometry allows accurate calculation of the interfacial area. It is also used in small-scale industrial absorption where a defined gas–liquid contact area is required. ANTICO WettedWall™ provides a clean, laminar flow interface ideal for scientific measurement and low-capacity absorption applications.
